Overheating
See signature for make and model. Isc 425 cummins. Have overheating issues in stop and go traffic. Fine on the highway even pulling the trailer loaded. So I take it to the local Kenworth dealer ...

I fail to see how the cleaning of the CAC helps engine cooling? On mine the CAC and radiator are in parallel. Wouldn't you need to be cleaning the radiator?
With a rear radiator (likely Freightliner chassis) the CAC is in front of the radiator. The two are in SERIES. Dirt is "filtered out" by the CAC. So the front of the CAC is what needs to be cleaned.
Usual way is to clean from above (bedroom/closet access).
Blocked air flow into the front of the CAC also blocks air flow through the radiator.
